The need for topological time and location information in mobile e-business applications

This paper combines two major streams of recent research-the concepts of new media and the paradigm of platforms for mobile e-business applications. It shows that the `time-space-intention´ topology has to be investigated in order to design successful e-business applications in mobile scenarios. The paper is divided into four sections: after a brief introduction, we apply a media reference model to show in which phases of a mobile e-business transaction the issues of personalization and individualization have to be analyzed and what new parameters of personalization and individualization have to be taken into account in mobile scenarios. We analyze which parameters for personal filtering mechanisms are critical for adequate decision making in mobile environments. Finally we describe an information filtering mechanism that is based on the agent´s `time-space-intention´ topology and the cross-agent `time-space-intention´ topology
